Ubuntu Security Notice 626-2 - USN-626-1 fixed vulnerabilities in xulrunner-1.9. The changes required that Devhelp, Epiphany, Midbrowser and Yelp also be updated to use the new xulrunner-1.9. Original advisory details: A flaw was discovered in the browser engine. A variable could be made to overflow causing the browser to crash. If a user were tricked into opening a malicious web page, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. Billy Rios discovered that Firefox and xulrunner, as used by browsers such as Epiphany, did not properly perform URI splitting with pipe symbols when passed a command-line URI. If Firefox or xulrunner were passed a malicious URL, an attacker may be able to execute local content with chrome privileges.
